21. A triangle has vertices (1, 5), (2, 7), and (6, 5). After a reflection and a translation, the
coordinates of the image are (5,-2), (6,-4), and (10,-2). Describe the transformation.
22. Find the image of the point at (4, -7) under the translation along the vector (a, b).

Answers

Answer 1

Answer:

See below

Step-by-step explanation:

I am not sure about number 22.  I think that they are asking you to apply the same rules to the point (4, -7), if that is what they mean, the answer is (8,10)

Step-by-step explanation:

In the equation for a line in the form y=mx+c, m represents the slope.

Therefore the slope is 3.

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + - 7 ← is in slope- intercept form

Coty painted a right triangle on paper. The hypotenuse of his triangle is 18 inches and one of the legs is 7 inches. What is the length of third side?

Answers

Answer:

G) 16.6

Step-by-step explanation:

We can use the pythagoriam theroem to solve the problem

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]a^{2} + 7^{2} = 18^{2}[/tex]

[tex]a^{2}[/tex] + 49 = 324

[tex]a^{2}[/tex] = 275

a = 16.6

Find the missing angle measurement in the triangle.

Answers

Answer:

the answer is C

Step-by-step explanation:

the right angle is = 90

the other angle= 55

so you add them together which makes 145

so subtract 180 which is = to a triangle subtract 180-145=35

Answer: C.)

Step-by-step explanation:

Triangle angles add up to 180 degrees.

The box is a right angle which equals 90 degrees.

55 degrees + 90 degrees = 145 degrees, but we need the sum to be 180, so we subtract 145 from 180 and you should get the answer of "35".

help????????????????????​

Answers

Answer:

x=11

Step-by-step explanation:

12x+2 and 2x+112 are opposite exterior angles so they are congruent

Answer:

x=11

Step-by-step explanation:

12x + 2 and 2x + 112 are vertical angles meaning that they are equal to each other so we set up an equation that says 12x + 2 = 2x + 112 and solve for x

12x+2=2x+112

step one subtract 2 from each side

12x=2x+112

step 2 subtract 2x From each side

10x=110

step three divide each side by 10

x=11

Can someone help me on this is for today pls!!!

Answers

Answer:

C

Step-by-step explanation:

The answer must be in square inches, not inches, so a and b are automatically wrong.

Couple of ways of doing it - the large triangles are congruent, so the area of each is the same. Since the area of a triangle is 1/2 base times height, the area of the 2 large triangles is just base times height, which is 18 * 11 or 198

Same principle for the smaller triangles at the top, area is 8 times 11, or 88. Add them up, you get 286 sq inches.
